Toyo Observe G3-ICE Winter Tire

Toyo has added a significant new tire to its extensive winter lineup – the Observe G3-ICE. The new tire is pinned for studs to help ensure maximum grip on ice and packed snow.
But it complies with the latest Scandinavian Tire & Rim Organization (STRO) regulation that calls for a reduced stud density, with a limit of 50 studs per square metre.

The Observe G3-ICE is a new design that incorporates Toyo’s signature Microbit Technology whereby crushed walnut shells are embedded in the tread compound. The edges act like tiny studs for improved ice traction.dsdfsdf

The compound also uses a high silica content to make sure the tread blocks stay flexible as the temperature drops.

According to the company, the location of the stud holes has been optimized to ensure “scratch effect” (road contact) despite the reduction in the number of studs.

Toyo says that in testing, the Observe G3-ICE stops a full car length shorter in snow and two car lengths less on ice than conventional studded winter tires with more than twice as many studs. And, it says this performance was achieved without sacrificing tread life or wet and dry handling.

Logically, with fewer studs, the Observe G3-ICE is also quieter and causes less damage to road surfaces.

In addition to the symmetrical location of the studs, the directional tread pattern includes wide evacuation grooves for slinging off water, snow and slush and a vast array of sipes with a wave-like pattern that provide added gripping surfaces and help stabilize the tread blocks.

The new winter tire is available in a variety sizes with a T speed rating to fit 14 – 17 inch wheels.
